My base module seems to be failed..
Is the all LH-SFI base modules (BM) compatible each others? Like w140 BM's work in 034/036 and vice versa? Is there any diffrences in BM's between engines (m119, m120)
I have access to BM for test purposes removed from e420 pn 011 454 97 32. Mine is 009 545 91 32
Are these interchangeable?
